Background

The original Coros Dura launched in 2024 as a budget-friendly bike computer with exceptional battery life, gaining popularity among long-distance riders and bikepackers. It was praised for its 120-hour battery life and lower price compared to competitors like Garmin and Wahoo. The Dura 2 Solar represents a significant shift toward a premium market segment, moving away from the budget positioning of its predecessor.
